Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with accompanying drawing: figure 1 As shown, the ordinary controller adopts a single current closed-loop control mode, and its maximum protection current parameter is constant. The controller 1 performs current detection 3 on the motor 2 and controls the motor 2 . The use of this control mode simply controls the overcurrent state of the motor, but does not conduct in-depth analysis according to the various requirements of the electric bicycle in actual use. In the actual process of riding an electric bicycle, the rider can maintain balance on the electric bicycle and the lowest acceptable speed is 5km / h. If the speed is lower than this speed for a long time, the controller has no meaning for the motor to maintain high power output. Large, and each electrical component is in an overcurrent state for a long time, which will directly affect the service life of the vehicle due to overheating and other...

Abstract

This invention relates to a brushless bicycle electric motor controller and its nonzero starting method. The controller is composed of: a casing, a main control panel, an erection base, an upper cover and wire bundle. A current-detection and a speed-detection are combined to form an over-current protection circuit and erected on the main control panel, from which circuit, led-out is a light-emitting diode (LED) for protecting the voltage of the accumulator from being lower than preset protection voltage, led-out is also a fault-displayer (LCD) for indicating the anomaly of level-signal of speed-regulation. In this invented controller, two closed-loop mode of current-detection and speed-detection are adopted to control the works of the motor. This ivnention has advantages of: intelligent, even output current, less damage to the motor, effective potection to the accumulator, long-service life of the controller, simple structure and reliable.

Description

technical field [0001] The invention relates to a controller structure of a brushless electric bicycle and a non-zero startup method of the controller. Background technique [0002] At present, the controller widely used in the electric bicycle industry is a brushed hub motor, and the corresponding one is a brushed controller. Because of its low cost and relatively simple controller structure, the brushed motor was used in electric bicycles earlier, but it also has its own defects, which limits its wide-scale application. With the development of technology and the increasing needs of users, a high-performance, high-reliability hub motor-DC brushless hub motor is gradually used in the electric bicycle industry. The motor adopts electronic commutation to replace the brushed motor. The carbon brush is used for commutation, so the commutation efficiency is high, and the motor will never wear out. The corresponding controller is a brushless electric vehicle controller. Although...
